Light weight hanging
As a PE designer and innovator I’m always exploring new ideas for PE devices. The OP has some steel rings and what looks like a cotton sleeve he would wear under the sleeves.
This sort of thing looks pretty safe as it doesn’t look like it would hinder blood flow or circulation. I’ve manufactured and tried a number of light weight devices myself. The issue with most of them it trying to conceal them under clothing so that you can wear them out in public. If that’s not an issue and you just want to wear it around the house then that’s a viable alternative to an ADS.
I made this double sided stainless steel ring that weights 2.25 lbs and is held together with a 3/16” dowel pin and a 1/4-20 socket head cap screw. We don’t currently make them as I just don’t feel like they would be big sellers.
